ESD Protection

Performance Graph - EPCOS / TDK E Series Multilayer Varistors

Electrostatic discharge (ESD) devices are fast and high voltage transients. ESD transients are frequently caused by touching a device or by contact with fingers. More than 15kV can be charged in a human body, thus a protection device for ESD requires withstanding high voltage and very short response time. EPCOS / TDK CTVS E Series Multilayer Varistors for automotive applications provide highly reliable ESD protection up to 30kV, according to IEC 61000-4-2, level 4 (8kV contact, 15kV air). The response time is <0.5ns.
